The Kammprofile Gasket is metal core that has serrations on the bolt load for compact seal at minimum stress. It is a cold flow, overcompression and blowout resistant. It also provides strong stability in handling and installation. Moreover, the unit provides seating imperfections to give tight connections and seals for low stress which are ideal for minimum flanges. It can resist maximum decrease in temperature and pressure.
The convex root core fills for the flange weakness and flange rotation and centering ring offers great gasket positioning. It has floating centering ring outside that is responsible for expansion and contraction. The device is used in applications such as standard ASME flanges, replacement for heat exchanger gaskets, seals weak flanges, vacuum up to Class 2500, resist cryogenics temperature of 2000°F (1090°C).
